Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a scaffold for assembling reinforcing bars used when assembling relatively large foundation beam reinforcing bars of a building made of reinforced concrete or steel reinforced concrete.

[Conventional technology and problems to be solved]

Generally, when assembling reinforced concrete or steel reinforced concrete building foundation beams, as shown in Fig. 7, first of all, at appropriate intervals along the length of the beam and on the throw-away concrete where the beam is placed, Arrange the stand 1 according to your heart. The stand 1 includes a base 2, a pillar 3 standing upright from the base 2, a guide portion 4 fixed to an upper end of the pillar, and a rod 5 vertically slidable in a hole of the guide portion 4.
And a main bar supporting member made of a cross member 6 orthogonal to the rod. As usual, the crosspieces 6 of these stands 1
The beam post 7 is arranged at a predetermined position and fixed with a wire, and the stirrup 8 is mounted on the beam post 7. However, if the height of the beam is more than 2 m, there is a scaffold for assembling the beam columns and stirrup, so carry a separate stepladder and place it on both sides of the position where the beam should be assembled before assembling the beam. It was usual to work, and depending on the height of the beam, the work had to be carried out in an unstable state where the step of the stepladder was stepped on, resulting in poor workability.

An object of the present invention is to provide a reinforcing bar assembly scaffold whose height can be adjusted according to the height of the beam reinforcement to be assembled.

[Means for Solving the Problems]

In order to solve the above-mentioned object, the scaffold for assembling a reinforcing bar according to the present invention is capable of being telescopically fitted to and fixed to a base member including a base and a pillar upright from the base, and a pillar of the base member. And each scaffolding assembly consisting of an upper member having lateral protrusions for supporting the plate on which the worker rests, is arranged on both sides of the assembly position of the foundation beam rebar so that the protrusions face each other. , The opposing protrusions are connected to each other by a bridging member.

An intermediate member may be further provided between the base member and the upper member to connect them.

Further, it is advantageous for each of the above members to be formed of a shape member which is telescopically fitted to each other except for the base, for the reason described later.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 shows a scaffolding assembly for rebar assembly according to the present invention, which is used for assembling a base beam rebar when the beam height is more than 2 meters, arranged on both sides of the beam rebar. 1
Is a well-known height adjustable stand as described in the prior art.

The parts of the scaffolding assembly for assembling each rebar will be described with reference to FIGS. 2 to 5. FIG. 2 shows a base member 12 including a base 10 and a column 11 standing upright from the base 10. FIG. 3 shows an intermediate member 14 connected to the base member 12. The stanchion 11 and the intermediate member 13 of the base member 12 can be made of a square pipe shape in which both are telescopically fitted (first
See figure). At that time, a plurality of rectangular holes 11a and 13a penetrating the square pipe laterally are formed in both of them at the same interval, and the base member 12
By moving the intermediate member 13 that is telescopically fitted in and up and down and inserting the stopper 14 at a position where the holes 11a and 13a are aligned with each other, the intermediate member 13 can be fixed at the adjusted height. Reference numeral 15 is a stopper for a square pipe or a round pipe of an upper member described later.

FIG. 4 is an upper member 16 having a straight column 17 and a lateral projection 19 for supporting a plate member 18 (FIG. 1) on which an operator rests. Similarly, the pillar 17 of the upper member 16 also uses a rectangular pipe shape member that nestably fits with the intermediate member 13.

After assembling the scaffolding assembly for reinforcing bar as shown in FIG. 1 by using the three members 12, 13, 16 configured as described above, the reinforcing bars for assembling each reinforcing bar on both sides of the position where the beam reinforcing bar should be assembled. The scaffolding assembly is placed with its lateral protrusions 19 facing each other and at appropriate intervals along the length of the beam. Next, both ends of the bridging member 20, which is also a square pipe, are inserted into the square pipes of the lateral protrusions 19 of the scaffolding assembly on both sides of the beam. If necessary, as shown in FIG. 6, a square pipe 21 is laterally welded to the support column 3 of the stand 1 so that the bridging member 20 can pass through the square pipe, or is generally used. If the square pipes are clamped to the support columns 3 using the scaffolding clamps, the scaffold for assembling the reinforcing bars becomes even more solid and stable. Finally, the plate material 18 is placed on the lateral protrusions 19 of the adjacent scaffolding assemblies to complete the scaffolding for assembling the beam reinforcing bars.

[Effect of device]

According to the present invention, each of the base member has a base and a pillar, and an upper member that is telescopically fitted to the pillar of the base member and can be fixed at a desired position of the pillar and that has a lateral protrusion. Since the scaffolding assembly is arranged on both sides of the assembling position of the beam reinforcing bars so that the projecting portions face each other, and the projecting portions facing each other are connected to each other by a bridging member to form the scaffolding for reinforcing bar construction, When assembling a large beam rebar with a length of 2 meters or more, the height of the scaffold can be adjusted by moving the upper member up and down with respect to the base member and fixing it to the desired height according to the height of the beam. In addition, since the bridging members are connected to each scaffold assembly, a solid and stable scaffold is formed, which improves workability and safety.

Further, in the present invention, since the intermediate member for connecting the base member and the upper member is further provided between the base member and the upper member, it is possible to assemble a beam having a higher height.

Further, according to the present invention, all the members except the base are made of shapes that can be fitted into each other in a telescopic manner to provide an economical and lightweight scaffold for rebar assembly.

Further, after the rebar assembly of the foundation beam is completed, the scaffold for rebar assembly can be disassembled and used again at another construction site. The stand 1 shown in FIG. 1 is embedded in concrete as it is even after the reinforcement of the foundation beam is assembled.
